Application filed July 5, 1913.

Vdie it known that I. ,kernen J. laioi-z, a eitixen of the Unit-ed States, residilng` at Indianapolis. in the county o1u Marion and State of Indiana. having` invented a new and nselul Intex-nah(ombnstion Engine, of which the following is a specification.

'lhe object of my invention is to produce a compact finotor, preferably of the internal combustion type, having a high power per unit oi' size and weight, ot.' the general type illustrated in my prior Patent No. 848,345, the construction beinp,` such as to be readily prmlucedand easily maintained. f

The accompanying drawings i-llustrate my invention. Figure 1 is an elevation of the inlet-and-exlnlust side of an engine emodying my invention, one of the exhaust connections having been removed; Fig. 2 is .an axial section through such engineon the line 2*.2 .of Fig. 3, the lower piston havmp; been ,emovcd and the connecting arm broken away; Fig; 3 is a mid-cylinder section at right angles to the plane of Fig. 2, with some departures from the general sectional plane. the planetary clement in thelower lei-'thand part being shown in full lines, and therefore departing from the main sectional plane, and the extreme lower lefthand portion displaying the port face of the rotary cylinder-body and thereby further' departing from the main sectional plane in a direction towardfthe observer; Fig. Atis an elevation of the port face of the rotary cylinder-body; Fig". 51 is a fragmentary section through the aXis of one of the planetary elements; Fig. 6 is a fragmentary elevation of the mounting of one of the supporting bearings for one of the planetary crank shafts; Fig. is aperspective of one half of the rotary cylinder-body; Fig. 8 is a fragmentary section showing the packing rings surrounding the passage which affords communication to and from a Combustion chamber-or cylinder; and Fig. 9 is a fragmentary-section of the connection between the pitmen of a pair of pistons and the main lever arm.

In the drawings, 10 indicates a body inember, conveniently a casting, provided with a central bearing 11 and an annular working face 12 which lies at right angles to the axis of-bearing 11., Casting` 10 convenientlyhas formed integral 'with it an inlet manifold i in each ofthese Patented Feb. 13, 191%. serial No. 777,446.

13 provided, in the present form shown, 55 with three branches 1l, each oi which communicates with an adjacent set ot bridged ports` 15, formed through the working tace l2. Casting 10 may also have formed integral therewith a water chamber .1G which lies against the wall of the casting which forms the working `lace 12. Bolted or otherwise secured to bodv 1() concentric with bearing 11 is a sprocket 17. Journaled in bearing 11 is a main shat't 21 which is the 65 power delivery shaft of the engine, and this shaft is provided with a circumferential flange and with one or more keys 23.

In my former patent the pistons and associated cylinders traversed an annular Sta- .70 tionary chamber which was concentric with the main shait, while in the present construction instead of this annular chamber I provide a-liat annular working face 12 and then provide what I call a rotary cylinderbody which is disk-like in form and is nia/de up of two similar and mating castings 30, 30. As is clearly shown in Fig. 7, each of these castings (and it will be here understood that the term castinpj7 is used in its 80 1broadest sense merely as a convenient form to indicate a single structure whether actually cast `or .otherwise produced) comprises a semi-circular plate 31, a similar semi-circular plate 32 spaced from plate 31 85 but parallel with it, an intermediate and connectingplate or plates 33, and cylinders 311, 31 which lie between the semi-circular disks 31 and. The cylinders 311, 34 are so bored as to come into alined pairs with adjacent open ends when the two parts of the rotary cylinder-body are bolted together, as is shown in Fig. 3, and mounted cylinders is a pistonl 35. .Each cylinder is provided with an inletand-exhaust port 3G which extends through` thc plate 31, and each of these ports, in the outer face of plate 31, is packed by packing rings. 37 which are preferably arranged in two or more concentric series, and this outer face of the two plates 31 together with the packing rings 37, is formed to contact and coperate with t'he workingl face 12 when shaft 21 is projected into `bearingv 11, and. the ports 3G are so arranged that each suc- `1015 ycessively comes into registry with the seve 'al sets of hridged exhaust ports 53S which are also fornied through the working face 1Q at proper points hetween the inlet ports.

4Journaled upon shaft 21 hetween flange 2;! and keys 233 is :1 hushing l1 upon which is secured the niain lever :11'111 l2 having oppositely projecting ends t3: Si. and pivotally connected to each of these ends til is :1 pair of oppositely extending pitlnen l-i. xach of which extends to and is pivoted upon a suitahle cross pin l5 earried hy one of the pistons 2&5.

Each plate lil is perforated at 51, and surrounding this perforation is a pocket 5:5 in which is :nounted :1 rotary hearing pocket 523 which carries a hearing 5st which is eccentric to the inain hody of the carrier 53. ln axial alinelnent` or thereahout, with the lperforation 51 is :1 perforation or pocket which extends through plate JBL), :1nd in this pocket is mounted :1 hearing carrier ott which arries a tanning 5T which is eccentric t.; the niain hody of the carrier. The arrangement of the two hearing carriers 52; and 5U is such that the hearings 5t and 5T will he in axial alineinent`r and hy rotation of the hearing carriersI the connnon axis of the two hearings 5l :1nd 5T inay he `shifted toward and from the axis of the n1ain shaft 2l. The crank shaft 5H is provided with a inedial cranked portion 5S). and at its ends is provided with spur pinion sprockets (St), tt). which, when tln` parts are asselnhled, lie on the planes of'the sprocket 1T and a corresponding` sprocket 1T to 'which referencey will he lnade later. ny suitahle ineans. as, for instance, fastening screws (il and (32 each extending through proper ones of :1 series of holes in the flange of its eooperating hearingl carrier, inay he provided for holding the l aring arriers 53 and 5t; in their angular :1djustn1ent. rThe various parts are so proportioned. as is evident from Fig. 5. that in assenihling thenl the hearing is first huilt upon the canked portion 5t) of the crank shaft 5h'. and the crank shaft with this hearing on it is'then tln'eaded through the pocket 55. which is large enough to pernlit this with proper nlanipulation. and then through the eyel in one end of :111 arni t'i-t. the hearing (t3 ieinaining in such eye :1nd heing held there by the flange tt :1nd the arin connecting thecranlwd portion 5T with the remainder of' the crank shaft 5H. As the crank shaft is thus put in place. the pinion sprocket ttt) and the left-l hand end of the crank shaft 5H are also threaded through the hearing 54: hearing pocket 52). and perforation 51` and the rotary hearing pocket 5X5 is fastened in the desired position in the pocket 5;) hy its screw 61. The hearing pocket 5i has a flange 5B which hears against a face of tl1\ arni tt-tto prevent, side play thereof. After the crank shaft is in place in the eye ot' the rod til,

:u'in ttt is caused to straddle the adjacent portion of lever lf2. and spacing washers tt; are inserted hetween the lever and the fingers of the pait (t3. Thereupon a pin tn' is inserted through one of these lingers and iliressed into the lever l2. said pin heing somewhat shorter than the distance between the inner 'faces of the two plates 3l and 2&2 of the rotating cvlinder-hody, then this has heen accomplished. `two bushings (is. tts are inserted inthe fingers ot' the yoke (i5 and sleeved over the pin tti', said hushings heiug so proportioned that when in place tne distance between their outer vertical faces will he exactly equal save for a When the parts have been thus far assenihled the othei hlfurcated end G5 of clearance space. to the distance between` the inner faces of the plates 31 :1nd 232. thus giving the lever l2 lateral hearing support.

l`he adjacent ends of each pair of pitinen ll are pivotall"attached to the ends 43 of the lever l2. as shown in Fig. t). These ends of the two pitinen ttare hifnrcated. the one to the right in Fig. l spanning the end t3 ot' the lei'er 42.111111 the one. to the left spanning the hifurcated end of the one to the right. steel sleeve ttl of the saine length as the width of the hifureated end of the pilinan `tst to the right in the ey at the end of the lever t2. and has an enlarged portion having :1 tight tit in such eye. A bronze sleeve ft2 has :1 loose fit within the steel sleeve 91. :1nd is of' the salue length as the latter. Each prong of the hifurcated end of the pitlnan 'it at the right is perforated hy an c ve slightly larger than the-middle enlarged portion of the steel sleeve 91. to allow the readvpassage of the latter into place. :1nd in each sueh eye is :1 hronze hushing 9?. which hasa sliding fit onthe end of the steel sleeve ttl anda tight tit in suchI eye. A1" pin -94 extendsthrough thefiiiside of the hronze sleeve '92 and through theV two prongs of the hifuwated end of the pitnian 1t-t to ythe left. one. of such 'prongs heing -suitahly threaded so that such pin' :nay he retained in place. Thus the pitinan tvlto the left is provided with a hearing on the inside of the steel sleeve 91. andv the pitnian -llto the right'with :1 hearing on the outside of such sleeve. f

I`he packing rings -37 are split and on their under faces are outwardly beveled as indicated :1t-71(Fig. S) and so proportioned as to fit snugly ag:1instftl1e external wall ofthe pocketdl (`otiperatn1g with the Lheveled face of ring 3T is an loppositely heveled outer face'of a ring 73 which is also rfated in the pocket 72 and lies against its hottoin. This ring 73 is also splitand circun:t'erentiallv compressed, so that hy its i' ing` this, the sha'lt 2l.

'radial expansion it will serve to urge the cooperating ring 37 outwardly at right angles to the working face of the plate 31 and into engagement with the working face l2 of the casing member l0.

l/Vhen the parts carried by the shaft 2l have been assembled in the manner described, the shaft is projected through bearing 1l and a chain 75 is mounted upon the fixed sprocket wheel 17 and upon the two now adjacent sprocket pinions 60, which lie free from the teeth of the sprocket Wheel 17. This brings the working tace of plate 31 into engagement with the working face l2, and thereupon a casing member Sl, which is provided with a bearing 82, is slipped over the rotary cylinder-body and the shaft, coming into contact with the working face of plate 3:2 (not for the purpose of making a gas-tight joint, but in or der to hold the parts in proper relation with eachother), inclosing the rotary cylinderbody and being attached t0 the main body casting l0 by suitable bolts 83. This body member 8l may be a casting or steel stamping, and carried within it is a sprocket wheel' 17 which is concentric with the bearing 82 and is like the sprocket Wheel 17, being formed to receive a chain 75 like the chain 75; for cooperation with the adjacent pinion sprocket G0 of the planetary crank shafts. I

A portion of the main plate of this body member 8l may be water-jacketed as indicated at 84. l

In operation, the fuel cycle is the ordinary ()tto cycle and the ports ot the several cylinders come alternately into registry with the several inlet and exhaust ports, the direction 'of rotation being indicated by the arrow in Fig. l and a complete cycle being performed during one-third oitI a rotation of the cylinder-body. Force applied by jn'essure exerted upon any piston, tends to swing lever 42 upon shalt 2l. This in turn exerts a force, either a pull or a push depending upon which piston is being acted upon, upon the arms G4, which. in turn, act upon the planetary crank shafts 58 so as to produce rotation thereof. Rotation ot these crank shafts causes 'the pinion sprockets GO to rotate within the chains 75, and, as these chains are held by the fixed gears 17 and 17, the resultant torce upon the planetary shafts is cirmnn'l'erential relative to the axis ot shaft :21, and, as the casing lO-84 is held againstv rotation at the supper-ting points, S, H (Fig. `l), rotation o'll shaft 2l is produced. ln the t'orin shown in the drawings, the engine is of the internal combustion type,v and therefore, as one is shown as provided with a suitable sparking current distributor 85 (Figs. l and Q) and spark plugs 8G are erovided at suitable mints each of .said l a ing n'ienibers mating on way of ill ust-rat-v spark plugs communicating through a suitable port 87 at proper times with the ports 36 of the several cylinders.

It will be readily apparentto any engineer that the precise method of induction and eduction of motive fluid to the cylinders is not important, and that modicttions to adapt the structure toany particulai md# tive fluid desired may be accomplished without. difficulty. In using the term gear in the claims, l intend to include both toothed and untoothed members, whether acting on one another directly or through the medium of a chain or belt. y

As indicated in Fig. the so-called silent type and in practice a. connection of this kind between the central gear and the planetary gears is preferable to a direct gear connection because in any direct gear connection there is some backlash which increases as the parts wear. lVhere the connection is a silent chain, however, there is a progressive engagement between the chain and the gears,- which eliminate'sl the back-lash and thus produces a very steady running machine.

I claim as my invention:
